Nanomaterials used as novel antimicrobial agents are developed to combat wide-spectrum bacteria as well as alleviate the problem of bacterial resistance to traditional antibiotics. Two-dimensional (2D) nanomaterials are regarded as promising and widely applicable wide-spectrum antibacterial nanoagents due to their outstanding characteristics, including large surface area, stable structure, good biocompatibility, and cheap raw materials, especially excellent photocatalytic or photothermal properties. The advantages of less resistance, rapid sterilization, local action mode, and non-invasive make 2D nanomaterials with photoinduced property stand out in novel sterilization agents. Here, we systematically summarize various kinds of 2D nanomaterials that were used in photoinduced antibacterial field and introduce the synthesis methods and physicochemical properties related to antibacterial capability. Besides, the sterilization mechanisms of different 2D nanomaterials are also introduced in detail including a direct temperature generation, ROS production or ROS-independent oxidative stress, or various synergistic antibacterial modes. Lastly, we have also discussed the current problems of 2D nanomaterials as light-inducing antibacterial agents and their future application prospects in the fields of biomedicine, sewage treatment, food, and other application scenarios. We envision that this review will assist investigators with quick and in-depth understanding of the latest progress in 2D nanomaterials for photoinduced sterilization, inspiring the development of multiply strategies to design and synthesize novel 2D materials with strong bactericidal capability and high biological safety, and expand 2D materials with photoinduced sterilization to more application scenarios.

用于光诱导抗菌应用的二维纳米材料

开发用作新型抗菌剂的纳米材料可对抗广谱细菌并缓解细菌对传统抗生素的耐药性问题。二维（2D）纳米材料由于具有比表面积大、结构稳定、生物相容性好、原料便宜，尤其是优异的光催化或光热性能等突出特点，被认为是一种很有前途且应用广泛的广谱抗菌纳米剂。具有较小阻力、快速杀菌、局部作用方式和非侵入性等优点，使具有光致特性的二维纳米材料在新型杀菌剂中脱颖而出。这里，我们系统总结了应用于光诱导抗菌领域的各类二维纳米材料，介绍了与抗菌能力相关的合成方法和理化性质。此外，还详细介绍了不同二维纳米材料的杀菌机制，包括直接产生温度、产生活性氧或非活性氧依赖性氧化应激，或各种协同抗菌模式。最后，我们还讨论了二维纳米材料作为光诱导抗菌剂存在的问题及其在生物医学、污水处理、食品等应用场景领域的未来应用前景。我们设想，这篇综述将帮助研究人员快速深入地了解用于光致灭菌的二维纳米材料的最新进展，
